This chapter provides you with information about hardware
installation procedures. It is recommended to use a grounded wrist
strap before handling computer components. Static electricity may
damage some components.

CPU
The VIA EPIA-N Nano-ITX mainboard includes an embedded VIA Luke
CoreFusion™ Processor. The VIA Luke CoreFusion™ Processor provides ultra-
low power consumption and advanced thermal dissipation properties and
features a fanless design. The VIA Luke CoreFusion™ Processor requires only
a heatsink to provide sufficient cooling.
Installation

CPU Fan:
The CPU fan runs on +12V and maintains the system cooling. When
connecting the wire to the connectors, always be aware that the red wire
should be connected to the +12V. The black wire should be connected to
GND.
FAN_MCM is a switch that is used by high-quality fans to monitor the system
temperature and will automatically adjust according to the environment.

MEMORY MODULE INSTALLATION
The VIA EPIA-N Nano-ITX mainboard provides one 200-pin SODIMM slot for
DDR266/333/400 SDRAM memory modules.
DDR SDRAM Module Installation Procedures
• Make sure the notch is on the proper side.
• Insert the memory module into the slot at a
30 degree angle (30 degrees from the
board). It should lightly snap into place.
• Push the module up against the board and
release your finger when the clips lock the
module.
Available DDR SDRAM Configurations
Refer to the table below for available DDR SDRAM configurations on the
mainboard.
Slot Module Size Total
SODIMM 64MB, 128MB, 256MB, 512MB, 1GB 64MB-1GB
Maximum supported system memory 64MB-1GB

CONNECTING THE POWER SUPPLY
The VIA EPIA-N Nano-ITX mainboard requires a special power cable adapter
to connect to a conventional ATX power supply. Before inserting the power
supply connector, always make sure that all components are installed
correctly to ensure that no damage will be caused.
Nano-ITX 12-Pin Power Connector
To connect the ATX power supply, make sure the power cable pins are
properly aligned. Then insert the plug firmly into the connector.

CONNECTORS
Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced IDE and Ultra DMA 66/100/133
controller that provides PIO mode 0~4, Bus Master, and Ultra DMA
66/100/133 functions. Up to four IDE devices can be connected to the
system.
The primary hard drive should always be connected to IDE1 as the master
drive. Both IDE drives can connect to a master and a slave drive.
IDE1

If two drives are connected to a single cable, the jumper on the second drive
must be set to slave mode. Refer to the drive documentation supplied by the
vendor for the jumper settings.
The mainboard has include IDE2 as 44-pin IDE connector for installing a mini
2.5 inches 44-pin IDE hard drive.
